11« ILLINOIS DAIRYMEN'S ASSOCIATION. 



DISCUSSION. 



Prof. Glover : — If you wanted to increase the percentage of 

 butter fat in the milk, wouldn't you select from the cows giving 

 the richest milk? 



Prof. Smith : — Certainly. 



Question : — Do I understand the reason they pasteurize their 

 milk in Northern Illinois is because it is held so long that lactic 

 acid gets started? 



Prof. Smith : — This much is true, that when milk as nor- 

 mally produced is so old that it sours, it is unfit to use when 

 pasteurized. 



Member : — You made a statement yesterday that milk should 

 not be used over twenty-four hours old? 



Prof. Smith : — Milked in a dirty stable, milk is hardly safe 

 for infants after thirty-six hours old. 



The President : — The situation in Northern Illinois is that 

 we have a great many four and five cow dairymen, who have 

 taken up the hand separator proposition. They undoubtedly be- 

 lieve it is the wisest thing for them to do ; they cannot afford to 

 hitch up a team and bring a few cans of cream, so they keep it 

 two or three days; it is sweet when delivered. We find by pas- 

 teurizing that cream we can make better butter than we can by 

 not pasteurizing it. I cannot see the force of your argument 

 about pasteurization. 



Prof. Smith : — Instead of meeting these men on the level 

 of two or three cows, get them to increase their herds and obviate 

 the necessity of the hand separator. 



The President : — What will you do in the meantime, close 

 up? 



Prof. Smith : — No, do the same as we have to, do without. 

 Mr. Chairman, I maintain that the ambition of the northern part 

 of Illinois should rise above the power of the hand separator.
